Application filed August 15,1924. Serial No. 732,298.

The soft fibre from between the rows of corn contains a moisture whichis imparted to the corn, causing the same to mold and decay. For thisreason a large quantity-of storedcorn soon becomes spoiled, andyofcourse, unfit for use. It may therefore be considered the primary objectof this invention to provide a simple means for removing the soft. fibreor what is commonly termed silk from between the ears of corn during.

the process of storing the corn.

A further object is the provision of means actuated by the cornelevating means for forcing a blast of air through the hopper associatedwith the elevator whereby the Figure 3 is "a sectional view onthe line 733 of'Figure 2.

Figure 4 is a perspective view of the hood andhthe flexible conductorassociated therewit V V I ,In the drawingsan elevator is indicated bythe numeral 1. The casing is centrally divided by a partition 2, and onthe opposite sides of the partition there are arranged the f leads of achain .3. Secured on thechain there are buckets 4 in which the ear ofcorn is deposited. The outer lead of the chain 3 is trained over asprocket wheel 5 journaled at the top of the elevator. The inner lead ofthe chain is journaled over a similar sprocket wheel 6 arrangedat theoutlet a mouth of the elevator and in a line with a downwardly inclinedwall 7 of thehopper 8 into which the ear of corn .is to be deposited.v 7Both leads of the chain are'trained around a sprocket wheel 9 suitablyjournaled in the hopper.

The hopper has swivelly secured to its lower and outlet end asemi-spherical casta metallic hood 12.

ing 10 to the sides of which there is pivoted the conductor spout 11 forthe ear of corn.

The spout or lower end of the hopper has its top open in the usualmanner but this opening in the present instance is closed by 12 isprovided with anopening surrounded by a fabric tubular member 14. Thefabric member 14 is removably connected with the hood and issecuredthereonlin any desired or preferred manner. "The lower inclinedwall 7 of the hopper; directly opposite the opening in the hood 12, isalso provided with an opening. This opening, however; is covered, by areticulated plate or screen 15 The sides of the hood are bolted, as at13, to the sides of the spout of the hopper. The outer end of the hoodand the said opening is surrounded by a flange 16 on the spout end 17 ofa fancasing 1 a 18. The flange 16 is; of course, secured to the'wall 7of the hopper 8.

The fan casing has its sides provided with 'the usual airinlet openingsand fhasjournaled centrally therethrough a shaft 19. On this shaftthereis fixed a spider member 20,

the same including ahub having arms radiating therefrom, and to each ofthesearms" there is secured a blade 21 which isprefen' ably of wood. 7

On the outer end of the shaft-19 there is secured a pulley 22, and onthe shaft 23 [for the sprocket wheel 6 there issec-ured a belt wheel 24.7 Around the-belt'wheel and the pulley 22 there is trained anendlessbelt 25.

Motion is imparted elevator inthe usual manner and is transmitted totheshaft for the fan for causing the latter to rotate-in the direction ofthe to the chainsof the arrow in Figure 2. The fan-forcesblasts of airthroughthe screen 15 to remove the sill;

from the corn. which slides on the ,lower inclined wall of the hopper 8.The silk is forced through the fabric tube 14, and the corn from whichthe silk has been removed is directed to the bin through the outlet ofthe hopper and thes'pout 11'.

It isbelieved froin'the foregoing description, when taken in connectionwith the drawings willfully set forth thfCOnStTllC' tlon and advantagesof my 7 improvementto those skilled in the art to which such in I'ventions relate. v 1 v Having described the invention I claim ing a fanfor injecting air through the screen 10 The combination With a cornelevator and into the bottom of the hopper and oper- Which includes theusual inclined hopper ated by the elevator, a hood closing the having anopen top and provided With a open top of the hopper and disposed at an 5delivery spout, and having an opening in its angle opposite the faninlet and a fabric bottom which is closed by a screen, of a tuberemovably secured on the outer face of 15 means for removing fibroussubstance from. the hood. v between the ears of corn in their passage Intestimony whereof I my signature.
